CVE-2021-1297
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMultiple vulnerabilities in the web-based management interface of Cisco Small Business RV160, RV160W, RV260, RV260P, and RV260W VPN Routers could allow an unauthenticated, remote attacker to conduct directory traversal attacks and overwrite certain files that should be restricted on an affected system. These vulnerabilities are due to insufficient input validation. An attacker could exploit these vulnerabilities by using the web-based management interface to upload a file to location on an affected device that they should not have access to. A successful exploit could allow the attacker to overwrite files on the file system of the affected device.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceDirectory traversal vulnerabilities in the web-based management interface of Cisco Small Business RV160, RV160W, RV260, RV260P, and RV260W VPN routers allow unauthenticated remote attackers to upload files to restricted filesystem locations and overwrite system files due to insufficient input validation on file upload paths.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the router modelLocate the physical device or check network inventory for the specific model: RV160, RV160W, RV260, RV260P, or RV260W. This vulnerability affects only these five models.Affected if Model is one of RV160, RV160W, RV260, RV260P, or RV260W
-
Check the firmware versionAccess the router's web-based management interface and navigate to the status or administration page to view the firmware version. Alternatively, use the CLI command 'show version' via SSH or console access.Affected if Firmware version is lower than 1.0.01.02
-
Verify web-based management is enabledIn the router's web interface, go to the administration or management settings and confirm whether the web-based management interface is turned on. This is typically found under 'Administration' > 'Management Access' or similar.Affected if Web-based management interface is enabled and accessible (the vulnerability cannot be exploited if this feature is disabled)
The environment is affected if the router model is one of the five listed models, the firmware version is below 1.0.01.02, and the web-based management interface is currently enabled.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data1.0.01.02
Apply Cisco's firmware updates for these router models. If patches are unavailable, restrict web-based management interface access to trusted internal networks only or disable remote management entirely.
